Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for USB-B-S-S-W-SM-R-TR is determined by the following critical parameters:

Electrical Compatibility: USB 2.0 specification, 4-position contact configuration, 30VAC rated voltage, and 1500 mating cycle rating.

Mechanical Compatibility: Surface mount technology, right-angle orientation, horizontal mounting feature, and solder termination method.

Environmental Compliance: Operating temperature range, material flammability rating (UL94 V-0), and contact finish (gold plating).

Functional Features: Board guide and solder retention capabilities.

Substitute parts must maintain identical values across all these parameters. Variations in insulation color, packaging format (Tape & Reel vs. Cut Tape), or manufacturer do not affect functional substitutability when all electrical and mechanical specifications align.

Parameter Comparison

Engineering Selection Recommendations

Samtec Inc. Substitutes (USB-B-S-F-B-SM-TR, USB-B-S-S-B-SM-TR, USB-B-S-S-W-SM-TR):

All three Samtec alternatives meet the complete electrical and mechanical specification set of the main part. These components are functionally interchangeable with USB-B-S-S-W-SM-R-TR. Selection among these Samtec options depends on insulation color requirements: white insulation (USB-B-S-S-W-SM-TR) matches the main part exactly, while black insulation variants (USB-B-S-F-B-SM-TR, USB-B-S-S-B-SM-TR) provide alternatives for applications where insulation color is not a design constraint. All Samtec parts carry ROHS3 compliance and MSL 1 (Unlimited) rating.

TE Connectivity Substitute (1-1734346-1):

The TE Connectivity part 1-1734346-1 shares all critical electrical and mechanical parameters with the main part. However, the operating temperature range is restricted to 0°C ~ 50°C, compared to the main part's -50°C ~ 85°C range. This substitute is suitable for applications operating within the 0°C to 50°C envelope. The part is supplied in Cut Tape (CT) packaging rather than Tape & Reel format. Current rating is specified as 1A for this component. TE Connectivity part carries ROHS3 compliance and MSL 1 (Unlimited) rating.

Selection Criteria:

For applications requiring the full -50°C to 85°C operating temperature range, select from Samtec alternatives. For applications limited to 0°C to 50°C operation, the TE Connectivity part is acceptable. Packaging format (Tape & Reel vs. Cut Tape) should be evaluated based on assembly line requirements and component handling procedures.

Frequently Asked Questions (FAQ)

Q: Can USB-B-S-F-B-SM-TR replace USB-B-S-S-W-SM-R-TR in all applications?

A: Yes, from an electrical and mechanical standpoint. The only difference is insulation color (black vs. white). If insulation color is not specified in your design requirements, this part is functionally equivalent.

Q: What is the significance of the packaging difference between Tape & Reel and Cut Tape formats?

A: Tape & Reel packaging is optimized for high-volume automated assembly lines with pick-and-place equipment. Cut Tape packaging is suitable for lower-volume production or manual assembly processes. The connector itself is identical; packaging affects handling and assembly methodology only.

Q: Is the TE Connectivity part 1-1734346-1 suitable for all temperature environments?

A: The TE Connectivity part operates from 0°C to 50°C. If your application requires operation below 0°C or above 50°C, this part is not suitable. Samtec alternatives support -50°C to 85°C and are required for extended temperature range applications.

Q: Do all substitute parts meet the same compliance standards?

A: All listed substitutes are ROHS3 compliant, UL94 V-0 rated, and carry MSL 1 (Unlimited) moisture sensitivity level. All parts are active in production status.

Q: What determines whether a part can substitute for USB-B-S-S-W-SM-R-TR?

A: Substitution is determined by matching USB 2.0 specification, 4-position receptacle configuration, surface mount right-angle orientation, solder termination, 30VAC voltage rating, 1500 mating cycle rating, gold contact finish, and UL94 V-0 flammability rating. Operating temperature range and packaging format are secondary considerations that may restrict substitutability in specific applications.

Q: Can I use USB-B-S-S-W-SM-TR (without the -R suffix) as a substitute?

A: Yes. The -R designation in the main part number indicates a specific variant, but USB-B-S-S-W-SM-TR maintains all critical electrical and mechanical specifications required for functional equivalence.
